I am currently running an experiment looking into the degradation of some toxic waste. We are using a consortium of bacteria to break it down in continuous flow through a set of bioreactors (buckets with a matrix for a bacterial film to grow on). What I am looking for is a pump that will provide water at a continuous rate of two litres every 24 hours, can only seem to find solutions much higher or much lower than this. I am trying to find a solution using another bucket and a tap to drip into the first bioreactor, but this is proving fiddly at best and not terribly consistent.
In the spoiler is a paint diagram of the current set up, any help or ideas would be great.
Other than that, anyone else have an interest in microbiology?
